I think Cristiano may have a point in that Aries generally follows the best practice of separating API and implementation into different bundles. This allows the implementation to be replaced without changing the API and sharing implementations through services means they can be replaced dynamically without causing clients to be refreshed. The bundle Cristiano was missing is an implementation and therefore there would not be a missing package import. I've not looked into it, but there may have been a missing service reference from the Blueprint impl bundle to the service provided by the proxy impl bundle. If Blueprint was managing the bundle then it would complain about missing services, but I guess Blueprint can't manage it's own service dependencies ;)
Maybe a note at the top of the downloads page would help. Anyway, Cristiano, I'm glad you found the problem :) Regards, Graham.
